# Calls to TrueConf Server via SIP/H.323

# Connecting to a conference

To make a call from a hardware or software SIP/H.323 endpoint (including TrueConf Group or TrueConf Videobar) to a conference hosted on TrueConf Server, use a call string in one of the following formats:

  • 00<Conference_ID>@<server>

  • 00<Conference_ID>@<server>:<port>

where:

  • <Conference_ID>conference ID

  • <server> — the server domain name or IP address

  • <port> — the connection port (used if the port is different from standard 5060 for SIP and 1720 for H.323).

For example:

001949195144@video.company.com

001949195144@video.company.com:1730

To join a PIN-protected conference from an SIP endpoint, it is necessary to add PIN, separated by a comma after the conference ID in the call string:

00<conf_id>,pin@<trueconf_server>:<port>

# Call to a TrueConf Server user

To make a call from the endpoint to a user registered on TrueConf Server use one of the following formats:

  • <TrueConf_ID>@<server>

  • <TrueConf_ID>@<server>:<port>

where:

  • <TrueConf_ID>user TrueConf ID

  • <server>— IP address or domain name of the server where the call should be routed

  • <port> — the connection port (used if the port is different from standard 5060 for SIP and 1720 for H.323).

For example:

james78@video.company.com

james78@video.company.com:5070

# Additional features

Additionally, to make a call via SIP, you can explicitly specify the protocol name (UDP is used by default):

00<conf_id>,pin@<trueconf_server>:<port>;transport=<protocol>

Some H.323 endpoints like Cisco also support call strings with double hashes ##. In this case TrueConf users and conferences can be called in this way:

<trueconf_server>##00<user>

<trueconf_server>##00<conf_id>
